In a deeply disturbing and almost surreal case reported from Yangzhou City in Jiangsu province, China, an eight-year-old girl Girl Vomits Live Worms for nearly a month. The medical anomaly was eventually traced back to an unlikely culprit—drain flies, also known as moth flies, commonly found in household sinks and drains.
The girl’s ordeal caught national and international attention after South China Morning Post (SCMP) reported the story, highlighting a severe infestation that stunned both her family and healthcare professionals.
Despite the horror of her symptoms—vomiting live larvae about a centimetre long—the infection was fortunately not contagious, as no other family member showed similar signs. The girl’s situation, however, serves as a grim reminder of how overlooked domestic hygiene issues can spiral into grave medical emergencies.
Girl Vomits Live Worms ?
What started as a series of unexplained stomach issues soon escalated into a full-blown medical mystery. The young girl, who had previously enjoyed good health, suddenly began to experience chronic nausea and bouts of vomiting. But the shocking part wasn’t the vomiting itself—it was what came out.
Instead of typical signs of indigestion or infection, the child began throwing up live worms. Each worm was about a centimetre long, alive and wriggling, causing alarm and confusion among her family members and the doctors treating her.
Her parents initially assumed it was a food-related illness or a typical stomach infection. They consulted several doctors, but none could pinpoint the cause of the bizarre symptoms. With each failed diagnosis, their anxiety grew, while the girl’s condition did not improve.

It wasn’t until she was taken to the Children’s Hospital of Soochow University in Jiangsu that the mystery began to unravel. There, one of the attending doctors suggested sending a sample to the local Centre for Disease Control and Prevention (CDC) for a more in-depth investigation.
Drain Flies: A Common Pest with Dangerous Consequences
When the sample reached the Yangzhou Centre for Disease Control and Prevention, a member of the staff made a crucial discovery. The live worms being vomited by the child were identified as larvae of moth flies, commonly known as drain flies. These tiny insects, often dismissed as harmless household pests, thrive in moist environments rich in organic matter, such as clogged or dirty drains.

Xu Yuhui, the department chief at the CDC, explained that the larvae had contaminated the underground water running through the building’s pipes. According to Xu, the worms might have entered the girl’s body through splashes of water when she brushed her teeth or flushed the toilet. This scenario, although rare, became plausible after tracing the environmental conditions in and around the girl’s home.
Moth flies are not known to transmit blood-borne diseases like mosquitoes, but their larvae can become problematic when ingested. In this case, the infestation appears to have been severe enough to survive and grow inside the girl’s digestive system. While such parasitic invasions are rare, they can lead to serious complications including intestinal blockages, malnutrition, and anaemia if not addressed promptly.
The discovery shocked the medical community because of how easily such an infection could be overlooked. Drain flies are so common in households that most people pay little attention to them. But under the right conditions, they can pose significant health risks, especially to children and those with compromised immune systems.
A Wake-Up Call on Hygiene and Domestic Awareness
This shocking incident has become a powerful wake-up call regarding domestic hygiene, especially in environments where children are present. It underscores the importance of regular cleaning, proper drainage, and vigilance when it comes to pests that thrive in overlooked corners of our homes. It also highlights the value of medical persistence—had the doctors not gone the extra mile by consulting the CDC, the root cause may have remained undetected.
Public health experts are now urging homeowners to ensure that drains, pipes, and water sources are kept clean and free from organic build-up that could become breeding grounds for insects. Regular disinfecting, use of drain-cleaning agents, and maintaining plumbing systems can go a long way in preventing such infestations. Furthermore, people are encouraged to use filtered or boiled water for activities like brushing teeth, especially in areas with older or compromised plumbing systems.
Another key takeaway is the need for better awareness among medical professionals about uncommon parasitic infections and infestations. While such cases are rare, early identification and intervention can prevent prolonged suffering and more serious health complications. Training and awareness at both the community and professional level could help ensure quicker diagnoses in similar cases in the future.
Parents and caregivers must also be attentive to unusual symptoms in children. Vomiting worms is not just bizarre—it’s a medical emergency that demands immediate and thorough investigation. The family’s insistence on seeking help and not giving up on their search for answers played a crucial role in eventually identifying the source of the problem.
This case, as terrifying as it is, ended on a positive note. Once the cause of the infestation was understood, the girl was treated accordingly, and her condition began to improve. Medical professionals provided her with antiparasitic medications, and hygiene improvements were implemented at home to prevent any recurrence.
But the psychological impact of the incident cannot be understated. For a child to go through a month of vomiting live worms is not only physically draining but also emotionally traumatic. Her recovery will likely require emotional support alongside medical care to help her return to normalcy.
In conclusion, this unsettling episode serves as a powerful reminder of the hidden dangers that can lurk in seemingly harmless places. Something as routine as brushing teeth or washing hands with tap water can pose threats if hygiene is compromised. While the case is rare, it is not an isolated one in the history of parasitic infestations, and it highlights the importance of awareness, proactive hygiene measures, and responsive healthcare.
The eight-year-old girl’s ordeal will undoubtedly leave a mark on how both the public and medical community view household hygiene and pest control. Hopefully, this case encourages more vigilance and prompts others to take steps to protect their families from similar threats hidden in plain sight.
